Coincheck, which was hacked in January 2018, losing altcoin tokens worth $530 million at the time, now joins the slowly increasing number of officially sanctioned exchanges serving the Japanese market.

The step is a milestone for the exchange and for online broker Monex Group, which bought Coincheck for a nominal $33.5 million in April.

Since the interim period, developers have slowly returned functionality to users and organized refunds of stolen coins.

Japan has sought to implement a licensing scheme over the past year in the wake of unease about exchanges’ security setups. Despite heightened legislation, smaller-scale hacks have continued, with fellow platform Zaif losing around $20 million last September.

On Friday, Cointelegraph also reported on a government investigation into crypto exchange security in South Korea, which found satisfactory compliance in less than a third of platforms.
